GTMS (Glass Metal Sealed) connector is a specially designed electronic connector that provides an indispensable solution for demanding high reliability applications due to its unique airtight packaging technology between glass and metal. Especially suitable for maintaining electrical connection stability in extremely harsh environments, such as environments with high humidity, corrosive gases, or fine particulate matter pollution. The excellent sealing performance of GTMS connectors ensures long-term stable operation of electronic systems under extreme conditions, thereby meeting the strict requirements of aviation, aerospace, military, and other critical fields.
Glass, as a high-quality insulating material, plays an indispensable role in electronic products, forming a good bond with metals and exhibiting excellent corrosion resistance. Glass also has excellent resistance to temperature changes and compression, allowing it to maintain stable performance under various extreme conditions. In electronic sealing components, the glass used is usually made of ground or granulated amorphous materials such as silicates, borates, and phosphates. These materials are heated to their melting point at high temperatures and then cooled to form a sturdy sealing structure.
The typical structural feature of GTMS connectors is that the metal conductor is fully surrounded by a glass insulator, forming a unique packaging form, in which the glass constructs a sturdy sealing barrier around the metal conductor. This precise design concept not only endows the connector with extremely high reliability and durability, but also effectively resists external environmental factors such as temperature changes, humidity, and corrosion. Other connection methods also include using O-rings to secure the glass sealing ring, or incorporating glass elements into the insulation design to further enhance the overall performance of the connector.

/Design Description/
Glass sealing technology can be divided into two categories: matched sealing and unmatched sealing (also known as compression sealing). In matching sealing, the thermal expansion and contraction coefficients of glass and metal materials are relatively close, usually controlled within 10%, which greatly limits the stress that the glass component can withstand, thereby ensuring the long-term stability of the seal. Relatively speaking, mismatched seals involve significant differences in thermal expansion coefficients between metal and glass. In the manufacturing process of connectors, the metal expands under heating and then tightly adheres to the highly stable glass during cooling, forming an extremely tight sealing structure. This unique sealing mechanism provides the connector with excellent moisture resistance, corrosion resistance, and mechanical impact resistance, enabling it to exhibit outstanding performance even in harsh working environments.
